How to remove USB Type C support for linux?

Hi,

we do not have USB Type C hardware support, so we do not need software support. Removing the driver and the related device tree entry ends in a non-bootable kernel. What changes have to be done to remove the USB Type C support?

Further infos:

- Custom Board based on imx8mn-ddr4-evk

Best,

Michael

Device Tree based on fsl-imx8mn-ddr4-evk.dts: If the part typec_ptn5110_1 is removed the kernel hangs during bootup.

Removed the following from the defconfig file.

CONFIG_TYPEC_TCPCI

CONFIG_TYPEC_TCPM

Removed these entries from device tree file
    
pinctrl_typec1: typec1grp {
    [..]
};
typec_ptn5110_1: ptn5110@50 {
         [..]
    };

    typec_ptn5110_2: ptn5110@52 {
        [..]
    };
&usbotg1 {
    [..]
};
